Useful LES tools in Fluent - Part 2

Posted August 2, 2013 at 04:27 by sbaffini (NuTBox)

A couple of routines i regularly use to output solution files in more manageable ascii files for post-processing in MATLAB. Of course this only makes sense when working in simple geometries where cells have regular patterns (e.g., simple boxes for computations in channels and ducts).

1) output.c: Used to dump an instantaneous field file

2) outputavg.c: Used to dump an averaged field file

More details can be found in the files

Useful LES tools in Fluent - Part 1

Posted August 2, 2013 at 04:15 by sbaffini (NuTBox)

Here i collect some very basic tools i used when performing basic LES computations in Fluent.

1) Custom field function for the Q criterion (q_crit.txt, to be renamed in .scm). Some Fluent versions (12, 13 and maybe 14) only have a "Normalized Q criterion" scalar, while previous ones simply don't have it at all. This custom field function is what i used in those dark days.

2) Several initialization routines (init*.c and scalefield.c) fully described in the files...
